6.0 Permits

6.1 General

A Permit is an isolation guarantee issued to a competent person under which

specified work is authorized on specific apparatus.

The issuance of a Permit shall be subject to the applicants acceptance of the

terms and conditions of issuance.

Permits shall be effective at the moment of issuance and shall cease to be

effective at the moment of surrender. The Permit shall be continuous for the

period between issuance and surrender.

All Permits shall be self-sustaining, that is, affording their own isolation and

not depending on the apparent isolation of some other Permit.

Under no circumstances shall any Permit be deemed to provide isolation for

anyone who is not authorized by the Permit Holder under their Permit.

RMSenergy Ltd.


It shall be recognized as a basic principle that all parties issuing and receiving

a Permit shall convey each to the other any and all information which might

assist the others to intelligently carry out their work or which might influence

their judgment, acts, or decision.

A Permit must normally be surrendered to the person from whom it was

received.

A Permit must normally be surrendered by the Permit Holder.

The Permit Holder and Safety Officer, must constantly maintain a means of

communication while the work is in progress, unless other arrangements have

been agreed upon between the Safety Officer/Permit Issuer and the Permit

Holder.

6.2.1 Responsibilities of the Safety Officer

The Safety Officer is responsible for the observance and enforcement of the

Safe Work Code.

The Safety Officer is responsible for the following:

- approve the removal of apparatus from service

- confirm the validity of the “points of isolation”,

- in the event of a change of the Permit Holder, log the time and name of the

replacement Permit Holder,

- maintain a list of personnel competent to be “Permit Holders”, and those

competent to “perform switching”.

The Safety Officer in dealing with applications for Permits will consider:

- the correctness and completeness of the information submitted with the

application,

- the impact of the removal of this apparatus from service on overall

performance of the power system,

- The suitability of the devices selected for the de-energization and safe

isolation of the equipment.

The Safety Officer on receipt of the Application shall refuse to grant a Permit

for the following reasons:

- the existence of a Permit, currently in progress, which includes devices

identified in the permit application.

- Refusal of the Application to conform with RMSenergy Ltd. rules and

regulations,

RMSenergy Ltd.


- Undesirable operating conditions which would result from the apparatus

outage,

- Use of non competent personnel.

The Safety Officer will arrange to have authorized persons perform switching

at the proper times and location.

The Safety Officer is responsible to ensure tags are installed on one line

diagram boards, SCADA systems and field devices.

The Safety Officer shall coordinate, direct and issue the Permit in accordance

with the Safe Work Code.

The Safety Officer shall not authorize any personnel to approach the apparatus

until the Permit has been issued and the terminal grounds, if required, have

been applied.

The Safety Officer shall be sure that every person acting under his/her

instructions, or taking part in the preparation, issuance, or surrender of a

Permit is competent and has carried out their part in accordance with the Safe

Work Code.

If the Safety Officer is not satisfied that all relevant conditions outlined in the

Standard Protection Code have been met, then, the Permit shall not be issued.

The Safety Officer shall furnish the Permit Holder and any other concerned

person affected by the work with sufficient information about the nature of the

work to be performed and the working conditions to enable them to judge

whether the Permit is in order.

The same person who issues a permit will be the one to whom it is

surrendered.

6.2.2 Responsibilities of Permit Applicants

The Permit Applicant is responsible to ensure the application is complete and

in accordance to the Safe Work Code.

All Permit applications shall be made to the Safety Officer.

All Permit applications shall include the following information:

- a switching procedure

- nature of the work

- identification of key personnel

- duration of the work,

- reason for the work,

RMSenergy Ltd.


- communications ID, path, phone numbers, etc.

Permit Applicant shall:

- furnish the Safety Officer with the complete information required with the

application,

- make the necessary arrangements with the Safety Officer and Permit

Holder for providing a means of communication between all parties

involved for the period during which the Permit is in effect.

6.4 Responsibilities of the Permit Holder

The Permit Holder shall be responsible to ensure a safe work environment is

maintained in accordance with the Safe Work Code and that all persons within

the isolation points of the permit are made aware of any dangers or risks

associated with the work to be performed. For complicated jobs or remote

work sites, the Permit Holder may designate a person to be their

representative at a designated site.

If the Permit Holder is not satisfied that all relevant conditions outlined in the

Safe Work Code have been met, then, the permit should not be accepted by

the Permit Holder. ( this is somewhat illogical since the Permit holder is the

originator or author of the permit in the first instance so he/she should be

certain of the nature of the work at the outset )

In addition to carefully observing the Safety Rules and Operating Procedures,

the Permit Holder shall:

- take out no more Permits than can be safely supervised,

- have no more crews working under his/her Permit than he/she can safely

supervise,

- prohibit work during his/her absence unless their responsibilities have

been transferred to a competent person,

- place any additional guards and warnings which are desired to clearly

indicate the safe work space.

The Permit Holder shall give clear instructions to the work crews(s)

regarding:

- all apparatus on which work is authorized,

- any neighboring apparatus which is “energized”,

- the safeguards provided against neighboring “energized” apparatus and the

precautions necessary when working near “energized” apparatus,

- the points of “isolation” and “terminal grounding”,

RMSenergy Ltd.


- the danger of sectionalizing the apparatus covered, thereby cutting off the

influence of required grounding devices.

Where work can be safely performed over a large area under one Permit, the

Permit Holder may delegate their responsibilities to a designated person at a

remote site. On acceptance, this designated person working under the

direction of the Permit Holder, is responsible to ensure that all relevant

conditions of the Safe Work Code are met at the remote site.

Should operating conditions make it necessary, the Safety Officer may request

that a Permit be surrendered. The Permit Holder shall be responsible to

surrender the permit as soon as practicable.

Before leaving the work site, the Permit Holder or designate must notify the

Safety Officer to advise of their whereabouts and the conditions of the

apparatus.

If the work has been interrupted, or if the work is to be continued on another

day, the Permit Holder must always report to the Safety Officer before

resuming work. The work crew(s) shall not commence work until instructed to

do so by the Permit Holder.

Should the Safety Officer and Permit Holder mutually agree that no

conditions could exist which could present a hazard to the workers, the public,

or the system, the requirements of 5.6 and 5.7 may be deemed unnecessary.

6.5 Transfer of Responsibilities of Permit Holders

The transfer of the responsibilities of the Permit Holder may occur only when

another competent person agrees to perform the responsibilities of the Permit

Holder at all times.

If for some reason, the Permit Holder must leave the work site, he/she may

transfer their responsibilities to a competent person. To make this transfer of

responsibilities, the original Permit Holder shall:

- arrange for replacement by another competent Permit Holder,

- explain all details of the Permit to the individual who is to act on his/her

behalf,

- advise the Safety Officer of this change and expected duration (who will

log the time, date, and name of the replacement)

- advise the Work Crew of the change.

To make a transfer of responsibilities, when the original Permit Holder is not

available, the original Permit Holder’s supervisor and the Safety Officer in

conjunction with the work crew(s) may make a transfer request. In this case

RMSenergy Ltd.


the original Permit Holder’s supervisor acts as the temporary Permit Holder

until the transfer is completed. When the original Permit Holder returns, the

supervisor must review all changes and updates with the original Permit

Holder before they return to the work site.

6.6 Responsibilities of Work Crews and Others

The work crew shall not commence work until instructed to do so by the

Permit Holder.

If the work has been interrupted, or if the work is to be continued on another

day, the work crew shall not commence work, or continue existing work until

instructed to do so by the Permit Holder.

Each member of the work crew is expected to fully understand his/her

responsibilities as required by the Safe Work Code. If his/her responsibilities

are not clear, he/she shall seek clarification from the Permit Holder.

Should any member of the work crew become aware of any condition which

could compromise his/her personal safety, the safety of others, or system

security, they are to immediately advise the Permit Holder or their designate

of this condition.

Work crew member(s) installing a personal shunt(s) shall, at the time of

installation, notify the Permit holder or his/her designate as to the presence

and location of the personal shunt.

Work crew member(s), having installed a personal shunt(s) shall, after the

completion of work, be responsible to remove the personal shunt(s) and notify

the Permit Holder or his/her designate that the personal shunt(s) is not clear of

the primary equipment.

RMSenergy Ltd.


9.0 ISOLATION OF EQUIPMENT

9.1 Electrical Devices

Electrical devices used as isolating apparatus to conduct work under terms of a

permit shall:

a) whenever practical, provide visible separation which can be positively

determined by inspection of each phase contact assembly;

or

b) in the case where isolation is dependent on electrical devices with

concealed contacts, then this isolation shall be verified by the use of an

approved potential test indicator on each phase assembly and the

application of “terminal grounds” prior to the issuance of the permit.

Approved isolating devices shall consist of one of the following:

a) electrically or mechanically operated switches,

b) approved equipment which allows for the disconnection and removal of

fusible elements or bus links,

c) cable elbows which can be disconnected from other electrical apparatus so

as to provide a positive visible separation,

d) “jumpers” which when removed establish a physical air gap equivalent in

distance with those safety standards referred to as the “absolute limits of

approach”,

e) single element or multiple disc type insulator arrangements approved for

use on GBLWP system,

f) draw out style breakers in which the breaker may be positioned such that a

separation between the bus and the breaker contact assemblies may be

visible and, if equipped, allow port shutters to close.

9.2 Blocking of an Isolation Device

When an electrically, mechanically, hydraulically, or pneumatically operated

device is used as a point of isolation pertaining to a Permit, operation of the

device shall be prevented by:

a) locking or blocking the device in the required position,

RMSenergy Ltd.


b) removal of the energy supply which operates the device, i.e. disconnection

of the electrical supply, closing of valves, unloading or discharging the

stored energy of springs, etc.

c) separation or removal of a portion of the operating mechanism, i.e.

separation of gear train assemblies or operating linkages, withdrawal or

the removal of approved insulated switchsticks,

d) any or all of the proceeding steps which achieve the purpose of preventing

the operation of the device.

10.0 TEMPORARY GROUNDING

10.1 General

These policies have been developed to provide a safe environment for workers

when working on isolated lines and/or equipment. Protection for the employee is

achieved by the utilization of the equipotential principle. These policies take into

consideration the available fault current levels, parallel lines, and return current

path resistance to power sources.

These grounding policies shall apply to all voltage classes employed by

RMSenergy for the transmission of electrical energy.

10.2 Equipotential Principle

The equipotential principle provides the worker with maximum “personal”

protection under any condition that could produce a potential difference in the

work area. The worker is fully protected by being within the equipotential work

area. This equipotential work area is established by providing a low resistance,

high current carrying capacity path (personal shunt) around the worker. This

effectively reduces the available current which can flow through the worker’s

body.

10.3 Terminal Grounds

“Terminal ground(s)” shall be installed at approved grounding location(s) which

by their application provide a current path to ensure the operation of protective

devices. The following conditions shall apply to the application of “terminal

grounds”.

Where “terminal grounds” are required, a minimum of one (1) terminal ground

shall be installed at an “approved grounding location”.

RMSenergy Ltd.


An approved RMSenergy grounding location shall be:

a) an engineered grounding grid assembly installed and verified by qualified

personnel

or

b) a grounding grid assembly, or combination of overhead neutral or ground

conductors which has been installed, certified, and approved for use.

The placement, removal, and location of any terminal ground shall be clearly

indicated on the approved switching procedure.

10.4 Procedures

Whenever work is to proceed under the terms of a permit, a zone of personal

protection shall be established prior to the commencement of the work.

Where work is to be performed on electrical equipment which:

a) forms all or part of a four (4) wire multi-grounded system,

or

b) lies within the bounds of a substation, switching station, or tap point,

where an engineered grounding grid exists. The zone of personal

protection shall be established by the use of a “personal shunt”.

Where work is to be performed on other electrical systems, the zone of personal

protection shall be established by the use of a “personal shunt” and “terminal

grounding”.

11.0 SWITCHING PROCEDURES

11.1 General

The switching procedure is a step-by-step plan used to ensure safe, secure and

coordinated switching operations on the power system.

A switching procedure shall be utilized whenever:

a) the intended work involves:

i) bypassing / paralleling on the electric power system

RMSenergy Ltd.


ii) separation of interconnected, paralleled, or looped

distribution feeders or transmission circuits,

iii) commissioning and/or testing equipment,

iv) the issuance of a Permit.

b) specified as a requirement by RMSenergy Ltd. approved practice.

NOTE: Under emergency condition, the use of an approved

switching procedure may be omitted; however, the steps

taken shall be limited to those necessary to safeguard life or

limit equipment damage.

Block, Tag, etc.

12.3 Procedure Preparation

Whenever practical, a single switching procedure shall be prepared to remove and

then return equipment to normal service.

Switching procedures shall be arranged in a logical, sequential manner. The

arrangement of steps shall address the processes necessary to de-energize, isolate,

ground, issue permit, cancel permits, remove grounds, reconnect, and re-energize

equipment.

Each switching step shall be limited in scope to describing a single switching

operation (i.e. open, close, etc.) and shall make reference to only a single device.

Additional remarks indicating the requirement to secure (lock, block, etc.) or tag a

device shall accompany the switching step and be considered as forming part of

the single switching instructions.

Where a single procedure cannot adequately encompass the steps necessary to

describe a complete project, the procedure originator shall ensure each inter-

related procedure stands on its own by the inclusion of “confirm” steps within the

procedure. These “confirm” steps shall clearly identify any abnormal operating

condition or execution/timing conflicts which must be considered prior to the

execution of the intended procedure.

Confirmation or “confirm” steps shall be incorporated into a switching procedure

whenever:

i. during the course of the procedure, the position of a device may

have been altered by testing or maintenance-related activities;

ii. points of isolation, established by other permits or procedures, are

to be shared by permits issued as part of the current procedure;

RMSenergy Ltd.


iii. notification of a unique operating condition or timing/execution

priority must be established within the current procedure or

between other inter-related procedures.

Notes shall be added to the procedure whenever it becomes necessary to bring

attention to or give further explanation to a specific switching arrangement. For

example, when a group of switching steps are to be performed in a simultaneous

manner.

12.4 Approval/Routing

All procedures shall be submitted to the appropriate Safety Officer for approval.

The Safety Officer shall then assign to the procedure, a unique file number (i.e.

procedure number) and return this number to the procedure originator. The

number applied shall be of a consistent nomenclature.

Should the procedure require revision, a revision letter (i.e. A,B,C…etc.) or a new

numbers shall be applied to the procedure by the Safety Officer and then returned

to the originator. Once revised, the procedure shall be forwarded to the Safety

Officer for further review.

12.5 Execution

Switching procedures shall normally be executed in a sequential step-by-step

manner. Steps involving the operation of energized equipment shall be confirmed

(as to the proper operation of the device) prior to the commencement of the next

switching step.

Deviations to the order in which the approved steps are executed shall require the

agreement of both the individual directing the switching operation and the Safety

Officer.

NOTE: Careful consideration and attention to detail must always precede any

change from the approved switching sequence.
